You were trying to pull the NTSC cable signal in from the lower RF
input, correct?
Regardless of what RF input you currently have it attached to, did you
attempt the same by switching to the other RF input? Try that too and
see what happens.

My goal is the have both NTSC and QAM cable on the same RF input, I
don't care which one that is. I'm also hoping that the 8VBS is on the
other RF input.
I forgot to mention that I did try switching between both RF inputs
while testing for NTSC signal, but thanks for suggesting that.
